ios - IBInspectable setTitle :forState on UIButton not working

Question

我正在尝试使用 Interface Builder 中的实时呈现为 UIButtons 实现一个可本地化的类。这是我到目前为止的代码:

@IBDesignable class TIFLocalizableButton: UIButton {

    @IBInspectable var localizeString:String = "" {
        didSet {
            #if TARGET_INTERFACE_BUILDER
                var bundle = NSBundle(forClass: self.dynamicType)
                self.setTitle(bundle.localizedStringForKey(self.localizeString, value:"", table: nil), forState: UIControlState.Normal)
            #else
                self.setTitle(self.localizeString.localized(), forState: UIControlState.Normal)
            #endif
        }
    }

}

布局在 IB 中正确更新，但文本未显示。我用 UILabel 创建了相同的实现，它确实有效: https://github.com/AvdLee/ALLocalizableLabel

欢迎任何关于如何解决这个问题的想法!

UIButton 类型应该是自定义的然后 setTitle 工作
